Treatment with N-bromosuccinimide (NBS) or N-chlorosuccinimide (NCS) of 1-subsituted 1-alkoxy-1,3-dienes, obtained by reaction of α,β-unsaturated acetals with LICKOR superbase, affords γ-brominated (chlorinated) α,β-unsaturated acetals or carbonyl compounds, according to the selected experimental conditions.

halogenation - unsaturated acetals - alkyl halides - carbanions - enones
